Powerful 3D Depth and Surround Sound Capabilities Users will have greater flexibility in the placement of their HW-E550 Surround Sound Bar with 3D Depth Sound - they can either place the sound bar horizontally below their TV or split the sound bar into two vertical speakers. By attaching each speaker to an included base, the soundbar can also morph into a traditional looking 2.1-channel system with half-tall speakers.
